摘要

摘要提出并计算了一种新型二极管激光器，其输出光束具有可扩展（基本无限）的孔径。这种孔径可以通过使用一个垂直腔来实现，其中一个反射镜采用表面衍射光栅的形式。针对 InGaAs/AlGaAs 异质结构和 0.98 µm 光谱范围所特有的材料参数，计算了拟议激光器的阈值电流密度和差分效率。

Wide-Aperture Diode Laser with Vertical Cavity

A new type of diode laser with a scalable (fundamentally unlimited) aperture for the output optical beam has been proposed and calculated. Such an aperture can be implemented due to the use of a vertical cavity with one of the mirrors in the form of a surface diffraction grating. The threshold current density and differential efficiency of the proposed laser are calculated for the material parameters characteristic of the InGaAs/AlGaAs heterostructure and the spectral range at 0.98 µm.
